Repeatability of 2D Magnetic Resonance Spectroscopic Imaging

Introduction Magnetic resonance spectroscopic imaging can be used for characterising both focal and non focal diseases throughout the brain as well as other areas of the body. 2DMRSI can potentially help evaluate diseases such as Alzheimer’s, tumour growth and epilepsy [1]. It is therefore important to determine the repeatability of MRSI, both at short and long term, as well as under differing clinical acquisition conditions. This study attempts to compare the repeatability between differing field strengths, echo times, pulse sequences and time points (short/long term).
